Crystallisation
Principle
Crystals can be grown in oversaturated salt solutions or by
evaporating the solvent. Crystals of the same substance have the
same shape, they differ only in their size. Crystals develop as the
particles approach one another due to the evaporation of part of
the solvent or due to a decrease in solubility at lower
temperatures. Salt crystals are grown from salt solution in
this experiment
